Make Finalize.wdl tasks volatile

[jamesemery]

I was using some tasks from here: https://github.com/broadinstitute/long-read-pipelines/blob/dc2cd65fe18e9301925f88cc79a3db601cd38029/wdl/tasks/Utility/Finalize.wdl (specifically FinalizeToDir) and I ran into some esoteric cases where call-caching was failing to re-upload results even when the underlying files had been updated. While the issues with call-caching might or might not be relevant here I actually think all of the upload tasks in that WDL should be labeled as meta { volatile: true } since their behavior depends on the status of files in the output folder which is not checked by cromwell for call-caching, so they should not be call-caching lest the state of the output folder be incorrect.
